The applicant, who is a specialist in this field, is not aware of the installation that has the distinguishing features described in this description and included in the claims.

SUMMARY OF THE INVENTION

One of the objectives of the invention is the creation of a mobile unit that provides metering, mixing and packaging of powdered, granular or other similar products, transporting these products in a certified 40-foot container, and working on a normal horizontal surface using all the necessary mechanisms, auxiliary devices and tools.

Another objective of the invention is the creation of a mobile installation, remotely controlled with full product control and product tracking, including real-time communication with a control center designed for this purpose, located remotely from the location of the mobile installation itself.

One of the objectives of the invention is to optimize production costs and the period from the beginning of product development to its entry into the market, which will ensure compliance with applicable laws and facilitate the management of the installation, thereby ensuring that the production line for the manufacture of the product meets the standards of each country of destination.

Another objective of the invention is to obtain the possibility of developing initial formulations of final products involving the use of raw materials from the area where the installation is mounted. Due to this, in the manufacture of products in each particular place, you can use the properties and functionality of the local raw materials of each country.

Finally, the object of the invention is the creation of a fast and efficient production plant, including with optimization of the assembly process, which will completely secure the start-up and transportation operations of the said plant.

The inventive mobile installation contains a supporting structure with the possibility of placement inside a standard undeformed sea transport container, made in the form of parallel tubes, accommodating all parts that are part of the installation and installed in a horizontal plane. The indicated parts include:

ί) the first zone for the acceptance and manual weighing of various components of the final product included in the product formulation and to be mixed and bagged, followed by transportation to the loading zone by means of a heavy raw material stacker;

ίί) a second zone containing a material loading zone, providing the possibility of placing powdery material already suspended in the first zone, a container of total weight; bookmarking the products in accordance with the recipe in the tray by means of a stacker, unloading the product from bags taken in the first zone, and then passing through a sieve with a feed into a pre-marked container;

ϊϊΐ) the third mixing zone, in which the container loaded in the second zone is transported and placed under the mixer of powdered products for mixing, during which the mixer grabs and sets the container upside down in a vertical position and returns the container to its original position after mixing product, then separates the specified container from the specified mixer;

ίν) the fourth zone for filling the bags, providing the possibility of placing the container,

- 1 020242 held by a system of teeth and turned 180 °, at the top of the bag filling machine, then moving on to filling and weighing the bags, followed by stitching and labeling;

ν) the fifth zone of metal detection, which prevents the presence of any metal particles in the bags and provides the possibility of manually palletizing the bags and cleaning the container for subsequent use.

The supporting structure is made in the form of parallel tubes and can accommodate all components of the installation. The design is made of several types of square pipes, supported by several support points, giving it rigidity. In a preferred embodiment, one of the sides of the structure can be disassembled into three parts forming the working area. In addition, the design is equipped with a ladder to access the upper part at one end of the platform in order to gain access to the product loading area. As already indicated, the assembled structure with folded sides can be placed in a standard size container used for shipping, preferably in a 40-foot sea shipping container.

In order to ensure identification at the weighing stage, prior to weighing, it is necessary to identify all the raw materials received at the warehouse using a bar-code marking in accordance with the manufacturer's instructions. The acceptance and weighing zone is made in strict accordance with the task of weighing the product, carried out separately on the hinged surface of the structure, where the operator will weigh the individual components used to obtain the desired formulation and place them in a bag. The weighed and closed bag is laid on a pallet together with the remaining bags that make up the batch. Everything happens under the control and control of a programmable logic controller (PLC), directing the operator’s work, recording all the actions performed and issuing markings to be applied to the bags and providing traceability.

The indicated markings corresponding to the weighed batch of ingredients and intended for its identification during the loading process are placed on the bags. The markings indicate the exact weight in kg and the batch is identified corresponding to the formulation in which the manufactured ingredient is included. Upon completion of the palletization, the pallet is sent for proper storage or lifted into the loading area using a stacker in order to continue the production process.

When the finished bags are placed on the loading platform, the desired container is placed on the loading platform. After making sure that the container is in accordance with the frequency counter, the container is lifted and closed with a tooth system in order to start loading. In the loading zone, one ingredient will be requested from the container at a time: they will read the barcode of the required ingredient and, if the code matches the code set by the system, issue a request to download the specified ingredient and start the download (by means of a rotary valve and sieve); in this case, the operator will cut the bag with a cutter suspended on a chain that prevents the torch from falling inward with the product, then pour the entire contents of the bag into the tray and lay the empty bag aside. The aforementioned discharge chute should have a grill and a suction port to prevent dusty material from escaping. The contents of the tray fall through a rotary valve onto a sieve. This operation is designed and calculated in such a way as to ensure the removal of any unwanted product that could get into raw materials at other stages of the production process. The sieve should be at a suitable height, allowing horizontal removal of the rotor for inspection and / or cleaning. After sifting, the product falls into the container placed under the sieve in an appropriate amount. The full volume of the container is hermetically attached to the sieve to prevent the exit of the pulverulent product during filling of the container. In order to provide feedback and tracking, the container must be labeled.

After filling, the container is transported to the mixing zone located under the mixer, and after the container is firmly fixed to the mixer, the container is turned upside down and the mixing process is started, which ensures homogenization of the product. The considered stage is essential for obtaining a quality product. For its implementation, a mixer is provided, equipped with three blades, which allows to make the process smoother, and an amplifier mounted perpendicular to the generatrix of the mixer, both elements are equipped with frequency variators that program their speed, operating time and modes. The combination of these measures ensures the proper course of the process. Reliable sealing of the mixer is obtained due to the special design of the seals, which ensures a long service life and air tightness. After a certain period of time and the completion of mixing, the container is returned to its original position, in which the container is separated from the mixer, then transported to the packaging area.

After the contents of the container are mixed and homogenized, the container is transported to the bag or bag filling zone, where, using the tipping system, the container is mounted on the top of the bag filling machine, where the product is placed in bags, then the bags are weighed. On the cone located at the top of the bag filling machine, a suction point should be used to suck in any powder material,

- 2 020242 which may form during the filling of the bags. The filled bags are sent to the stitching and marking zone for stitching by means of a stapling machine suspended on a rotary device.

All bags that have already been sewn up pass through the metal detection zone, for which the bags are placed on a conveyor belt moving in the longitudinal direction through the detector, which eliminates the possibility of any metal particles in the bags. Then the bags leaving the detector are palletized manually and marked to identify the party to which they belong. After emptying the container, it is cleaned manually using a suction vacuum device. For convenient performance of the specified task, the operator must be on the platform. The container is then provided with a label indicating that the container is clean and ready for reuse.

The described installation is made with the possibility of placement and transportation in a standard 40-foot container, along with all the necessary mechanisms, auxiliary devices and tools. At the same time, the installation is designed for indoor installation with protection against atmospheric effects, in a ventilated place and on a flat floor that can withstand the indicated loads.

Traditionally, in installations for mixing powdered products, it is provided that the various steps of mixing the product are carried out vertically; in other words, transitions from one stage to another occur from top to bottom using gravity. In the line under consideration, a different principle is applied - the transition between the stages is carried out horizontally, due to which, due to the simplification of the process, operation, transportation and management are facilitated, and without compromising safety and poor tracking. This allows to minimize the errors of the personnel employed at the installation, to facilitate feedback on the compliance with the design technological sequence of operations, as well as to perform the necessary actions related to monitoring and control from the central station.

In addition, excellent cleanliness is ensured at the installation site due to the attractive design of the equipment and environmental protection measures that provide for the proper management of waste generated during operation of the installation, i.e. bags that are pressed each shift for subsequent disposal. There are no other sources of harmful effects on the environment, since when the unit is put into operation, acceptance is carried out, which assesses compliance with environmental requirements related to air pollution, liquid and solid waste, noise levels and the presence of undesirable odors.

Another advantage of the proposed installation is the ability to monitor installed equipment, organize replacement of spare parts, as well as preventive, diagnostic and repair maintenance, which eliminates any possible malfunctions, thereby ensuring the constancy of remote control of the process without interruptions in the manufacture, calibration and maintenance of the equipment.

In the described installation, by means of a tracking system, it is possible to identify each product throughout the food processing chain, which gives an additional guarantee of the safety of all manufactured products and the high quality of both technological processes and the final product. As a result, it was possible to control the quality of manufactured products directly at the place of manufacture and with connection to a control station.

A detailed description of one of the embodiments and an example of its practical application

As shown in the attached drawings, a mobile unit for dispensing, mixing and packaging powdered products is characterized in that it contains a supporting structure (1) and the following zones: reception and weighing zone (2); loading area (3); mixing zone (4); bag filling zone (5); zone (6) stitching and labeling zone; metal detection zone (7); palletizing area (8); cleaning zone (9).

As shown in FIG. 1, the supporting structure (1) contains several square pipes (11) resting on several support points (12) having an adjustable height, several articulated joints (13) and a ladder (14) equipped with a protective handrail (15). The dimensions of the structure do not exceed the dimensions of a standard 40-foot container, so that in a condition for transportation (Fig. 2), the dimensions of the structure make it possible to transport it in a container of standard sizes.

According to one embodiment, the structure (1) is made using square stainless steel pipes. The bottom of the structure is made of profiles with layers of carbon steel. Structural profiles and cross members are made of square stainless steel pipes. The structure (1) is based on six support points with adjustable height, on which a metal sheet with rhombic corrugation is located, on which people and cars can move. The board (16) is made with the possibility of folding in three sections and is also made using a square pipe and a metal sheet with rhombic corrugation. To facilitate installation and positioning, folding these boards by means of the aforementioned articulated joints is carried out using a series of collars.

The staircase (14) is made of stainless steel, with the exception of steps made of stainless steel using non-slip sheet metal. A rectangular platform is provided at the end of the stairs to provide access to the upper part of the platform. The upper part and the ladder are equipped with a protective handrail (15), enclosing the entire perimeter and made of a square stainless steel pipe.

As shown in FIG. 3, the acceptance and weighing zone (2) contains a rectangular base (21), a set of lifting devices, a series of profiles (23), a safety railing (24), a stacker (25) of heavy pallets and scales. In accordance with one embodiment, the weighing is carried out using commercial scales specifically designed for weighing, which are associated with a marking system and a control and measuring system.

By means of a loading stacker, the weighed product is transported to the loading section to a maximum adjustable height, with a maximum load weight also adjustable.

In FIG. 4 shows a loading zone (3) comprising a loading tray (31), a rotary valve (32), and a sieve (33). The product is supplied through a stainless steel tray (31), equipped with an opening on the side and a shelf that runs across the entire surface and is used for packing bags, with the subsequent opening and unloading of the contents. Inside there is a lattice that traps foreign particles. According to a particular embodiment, the filter width is 8 mm, and the width can be increased or decreased depending on the specific technical conditions for each installation specified by the user or the client.

In the lower part of the tray (31) there is a rotary valve (32), which provides product supply to the sieve (33). In the upper part there is a movable vacuum device for extracting powder.

A rotary valve (32), all parts of which are in contact with the product are made of stainless steel, is located between the loading tray (31) and the sieve (33). The valve contains eight rotating blades driven by a worm gear motor. The tightness of the shaft is ensured by the injection of compressed air near the seal stop. The valve rotation speed is constant to ensure uniform and continuous supply of the product to the sieve (33). The design of the rotary valve allows quick disassembly and cleaning due to easy access to the corners, as well as due to the finishing of the inner surface.

Due to the centrifugal effect used in the sieve (33), substances of various sizes, as well as the product itself, come through the filter in accordance with the technical specifications of the user or client. The sieve (33) is equipped with an additional tray in which the product is unloaded and which provides connection to the container (100).

The specified tray provides a transition from a rectangular outlet of the sieve to the round opening of the container. The specified round zone is equipped with a ring with a flexible gasket, which allows to obtain an airtight seal, as well as a set of sealing pneumatic controlled clamps holding the container during its loading.

In addition, in this area there is a ventilation hole and a sleeve filter. The purpose of this vent is to release excess air generated during product loading.

The bottom provides for the placement of a pneumatically controlled lifting table on which the container (100) is mounted. The purpose of the lifting table is to lift the container and apply pressure to the gasket until the clamps are closed.

The operation of the container holding system (100) in the loading zone (3) takes place in the following sequence.

1) Placing the container at the indicated position in the zone. For this purpose, guiding elements are placed on the bottom above the lifting table.

2) Lifting the table until the container applies pressure to the pad of the filling tray.

3) Actuation of sealing clips.

Holding the container (100) during its loading is carried out by means of a set of pneumatically controlled clamps. The clamps are single-acting clamps with a mechanical locking device that has fault tolerance in the sense that the resulting fixation will be maintained even if the air pressure drops. As soon as the fixation state is reached, the action of external forces on the holding lever will not lead to the cylinder retracting back. The clamp can only be opened by activating the upper chamber of the cylinder.

The clamps are equipped with inductive detectors to detect the condition of the clamps - open or closed. Sealing clamps have abutment teeth where height adjusters are used to adjust the tightening torque of the gasket.

In accordance with the described private embodiment, which is not restrictive, the lifting table (101) used to lift the container (100) is made in the form of a stainless steel plate. At the bottom there are two pneumatic cylinders with inductive detectors to detect their condition - open or closed. The specified platform is equipped with load cells for weight control at the end of loading the batch of the product and identify possible errors related to the lack of any ingredients in the process of monitoring the filling process. In addition, the sensors make it possible to verify the complete emptiness of the installed container before filling it.

As shown in FIG. 5, the mixing zone (4) is formed by a mixer (41) containing a cylindrical container (42), a low-speed central shaker (43), side booster (44), several clamps, a ring containing an airtight seal (46), a lifting table (47) , two welded half shafts, two bearings with bearings, a planetary gearbox controlled by a hydraulic motor, and a mixer ventilation system using a side filter that is automatically activated the moment the mixed container is released to release the product and preventing overpressure in the mixer (41).

It is preferable to make the mixer (41) stainless steel, while in this particular embodiment, the mixer comprises a cylindrical container (42). In the lower part of the mixer there is a low-speed central shaker (43) containing a three-blade rotor driven by a gear motor with a frequency variator.

In addition, the mixer (41) includes a side amplifier (44), containing a shaft with several blades, each of which is equipped with two blades, driven by a motor with a frequency variator.

A clip is placed in front of the specified amplifier (44) in case it is necessary to replace the amplifier system in the future.

On the cylinder body, at the end opposite the central shaker, a ring is provided to accommodate a gasket for the container. In addition, there are a number of holding clamps similar to those described with respect to the loading zone (2), as well as a lifting table (47) with the same functions as the table described above (101) in the loading zone (2).

The rotation of the mixer occurs through two axles located on the cylindrical / vertical part, with one of the axles resting on a bearing with bearings, and the other on a planetary gearbox controlled by an engine.

In a preferred embodiment, a hydraulic gear motor is used, however, the use of an electric or any other suitable motor is perfectly acceptable. To ensure the rotation of the specified gear motor, it is envisaged to be placed in the corresponding column in a hydraulic unit, consisting mainly of a tank with a gasket and a cover. In addition, there is a gear pump with a socket and a coupling for connecting to an electric motor. In addition, there is also a base plate with an adjustable safety valve and three pneumatically actuated valves to control the operation of the hydraulic motor. There is also a flow regulator in the line to control the speed of rotation, with a stop at any pivot point, depending on whether the mixture is optimal. The hydraulic motor is used as a brake device to prevent the mixer from moving if the gear pump stops intentionally or as a result of a power outage. There are also position sensors in the position corresponding to the fixation of the container, and in the position with a rotation of 180 °. Specified

- 5 020242 the hydraulic unit is connected to the hydraulic unit located in the bagging zone, while both units and only one unit can work at the same time.

In FIG. 6 shows a bag filling zone (5) comprising a discharge chute (51) and bag filler (52).

The container coming from the mixing zone, already described in connection with the previous step, enters the lifting system of the bag filling machine, comprising a stainless steel conical tray, rotatable around a shaft fixed to the L-shaped lever.

The tray (51) is equipped with a ring with a flexible gasket to obtain an airtight seal, as well as a set of sealing clips with a pneumatic drive that hold the container during unloading. In this zone there is a ventilation hole with a sleeve filter with a diameter of 50 mm. The purpose of this vent is to release excess air generated during the discharge of the product.

The bottom provides for the placement of a pneumatically controlled lifting table on which the container is mounted. The purpose of the lifting table is to lift the container and apply pressure to the gasket until the clamps are closed.

The operation of the container holding system in the unloading zone occurs in the following sequence.

1) Placing the container at the indicated position in the zone. For this purpose, guiding elements are placed on the bottom above the lifting table.

2) Lifting the table until the container applies pressure to the discharge tray.

3) Actuation of sealing clips.

At the top of the tray (51) there is a throttle that closes during the entire lifting process and opens when unloading. The damper is pneumatically operated. An unloading device controlled by an external gear motor is placed in the tray.

In addition, the tray (51) has a central axis with air outlets used depending on the specific product, to ensure the unloading of the specified product, as well as shock and vibration devices to perform the same functions.

The lifting and rotation of the discharge tray is carried out around an axis, one of the ends of which is mounted on a planetary gearbox driven by an engine. The rotation is approximately 155 °. The gear motor is placed on one side of the L-arm and controlled by a hydraulic unit similar to that described above in connection with the mixing zone, preferably using a hydraulic motor.

The structure of this section includes a pneumatically controlled vibrator used to eliminate congestion that may occur during product loading.

Container retention during unloading is carried out by means of a set of pneumatically controlled clamps. The clamps are single-acting clamps with a mechanical locking device that has fault tolerance in the sense that the resulting fixation will be maintained even if the air pressure drops. As soon as the fixation state is reached, the action of external forces on the holding lever will not lead to the cylinder retracting back. The clamp can only be opened by activating the upper chamber of the cylinder.

The clamp is equipped with a pneumatic cylinder providing a certain force sufficient to fix the container. The clamps are equipped with inductive detectors to detect the condition of the clamps - open or closed.

Sealing clamps have abutment teeth where height adjusters are used to adjust the tightening torque of the gasket.

In FIG. 6 also shows a stitching and marking zone (6) containing a rotary device (61) with a stapling machine (62) attached to it.

The bag filling machine is a commercial weighing and packaging machine with its own electronic equipment, characterized by ease of use and large information capacity. Among its working functions are the following: display of the current weight; display of previous weight; display of the number of units packed; display of the total weight of the packed units; high concentration flow control; low concentration flow adjustment, automatic adjustment of high concentration flow on the dispenser; automatic zeroing at the beginning of the cycle; possibility of manual start; the ability to cancel dosing; programming of estimated weight, dosing of high concentration and dosing of low concentration; initial delay programming; end delay programming; programming the number of packages, programming the weight to be packed; vibration loading, adaptation to bags with opening upon request and loading by means of an endless shaft.

In FIG. 7 shows a metal detection zone (7) comprising a conveyor belt (71) driven by a gear motor (72) and a metal detector (73).

After the bags are sewn up and marked, they are placed on a conveyor belt driven by a gear motor, and a metal detector is installed in the middle of the belt so that the conveyor belt passes through the specified metal detector along its entire width.

As a metal detector, a commercial device with a data output device connected to a computer system is used. A barcode reader is provided next to the metal detector to read all bags passing through the detector and identify the bag to be rejected if metal is detected in it.

The palletizing area (8) contains a set of pallets and a pallet weighing scale. After the bags have passed through the metal detector, they are stacked on pallets until the maximum possible weight is obtained. Pallets are weighed using weights to determine the weight of each unit.

The cleaning zone (9) contains a vacuum device (91) and several containers (92).

In the cleaning zone there is a hollow tube for vacuum aspiration of all containers. To facilitate movement and manipulation, the tube is suspended from a rotary device.

A single-phase type manual vacuum device is used to ensure safety, which is certified for operation in explosion-proof areas and is designed to collect liquid and / or powder materials. A vacuum device is a commercial device whose specifications are subject to change.

The containers (100) are in the form of a vertical cylinder with a capacity that provides the required production volumes, and are equipped with all the necessary components, such as a ring and a lid with a handle located on top, as well as four lower supports on which swivel wheels are mounted, which facilitate the movement of the container.

Auxiliary systems and equipment necessary for the normal operation of the installation

These include an oil-free air compressor, which provides air supply to all components of the installation equipment along the line going from the compressor chamber through a metal pipe through the entire structure in which the equipment is placed, with branches to each section and using a quick coupler and a shut-off valve.

The supply pressure is a maximum of 8 bar, with corresponding pressure reducers placed at each point of use. A commercial type air compressor is used, mounted above a horizontal soundproof oil-free tank. Of course, if the zone in which the installation is to be mounted already has its own compressor system, this part will not be included in the final installation.

Installation management and control systems

Technological operations are controlled by a central programmable logic controller (PLC), which is responsible, in essence, for dosing, monitoring all the individual stages of the process and compiling a list containing all the main parameters of the process of influencing the product. All these elements are included in the communication system in order to gain access to all data coming from the central station of the group, while control is carried out from the central station.

To solve this problem, a set of individual stations is provided with software that meets the requirements for data input / output, providing the ability to track the progress of the process, while the PLC controls the specified input / output using the program and the standard process that should accompany the product.

The same information will be displayed on each of the display nodes - this is the same information that can be seen in real time from anywhere on the Internet, with the difference that the corresponding operator can only manage the part that corresponds to the installation where he himself is.

The following information will be displayed on the displays:

Production tasks must be introduced daily from the operations center through the ZSEL-system (supervisory control system and data collection). To all of the above, the following phased separation of the sequence of work.

Weighing: in the process of weighing, the device ΟΌ81.2 connected to the general electric panel is used. located near the safety rail, where the following equipment is located:

marking reader;

marking machine;

display;

balance with data connection.

At this terminal, the PLC performs, inter alia, the following functions.

1. The operator reads the recipe on the display, which should be obtained with stirring.

2. The operator makes the product in accordance with the instructions on the display. Then, if the product has a barcode, the barcode will be read by the reader; if reading is not possible due to marking problems or technical malfunctions, the operator enters the barcode using the keyboard.

3. As a result, the printer prints a label that the operator sticks to the filled bag. In cases where full bag filling is not required, the procedure is the same, except that the desired weight will be displayed. The operator carefully opens the bag of raw materials and places an empty bag on the scale, then the operator, using a shovel, adds the product until the weight is reached in accordance with the weight on the display. Upon receipt of the indicated weight, the printer prints a marking applied to the bag with the desired recipe after it is closed. Then print the second marking, applied to another bag of raw materials. The operator places the weighted filled bags and prescription bags on a separate pallet called the prescription pallet by the applicant.

4. The above steps are repeated for each of the components shown on the display until the desired recipe is obtained. As a result of these actions, a pallet called a prescription pallet and the remainder of the raw material from which the ingredients were taken are obtained.

5. The PLC recorded the following parameters: ingredients, batch code, quantity with a margin of error, and manufacturing time.

Dosage: The prescription pallet is transported using a stacker to the loading area, where the operator removes bags from the pallet one at a time. A control panel is located next to the download area, containing:

marking reader;

touchscreen;

buttons.

The actions performed under the control of the central PLC of the installation include the following.

1. The operator enters the number of the container to be loaded.

2. The operator places the bag on the horizontal loading part and reads the dosing marking by the reader. After processing in the PLC, the component indicated in the list will be displayed in green on the display, after which the operator opens the bag and pours its contents into the loading zone.

3. If there is an indication of the exact positioning of the container on the base, the sieve, rotary valve and vacuum device are automatically started.

4. The PLC begins to enter the individual components of the formulation, continuing it until completion of the formulation.

Mixing: the purpose of this step is to homogenize the various components of the formulation and add them to the dosing process of the contents of the container. To ensure control of this process, a control panel is connected to the central PLC and equipped with the following elements: display.

At this stage, the following procedure has been adopted: the operator checks the presence of the recipe on the display after entering the container number. If the container matches, the process continues with

- 8 020242 completion of the following steps.

1. The container is attached to the mixer, after which a message appears on the display ready to mix.

2. From this moment, the central PLC proceeds to check the following parameters:

a) the speed of the high speed shaker and the connection times, the speed of the low speed shaker;

b) tilt, if applicable. Three angles of 30 °.

3. In other words, the PLC proceeds with the mixing program using various mixer parameters, depending on the type of product to be homogenized, with the registration of the time and time during which it was carried out.

4. Upon completion of the mixing program, the mixer separates the container from the mixing head with an indication of the indicated action on the display and by means of a sound signal, if any. At this stage, the real-time PLC performs full monitoring of each phase until the mixer opens, followed by separation from the container.

Filling the bags: at this stage, performed after the homogenization of the product is completed, the product is placed in individually weighed bags, checking for metal particles, then bags are marked with all the parameters used in the process. The control panel corresponding to this stage is equipped with the following equipment: marking machine:

touchscreen;

buttons

balance with data connection.

The entire unit is connected to the central PLC, and actions similar to those described below are foreseen.

1. The container is brought to the tipper and its number is displayed. If the number is correct, start the process.

2. After the container is attached to the discharge chute, the hydraulic mechanism turns the container upside down.

3. At this point, after the operator places the bag in the hole, filling of the bags begins.

4. The bag filling device starts filling the bag with a predetermined quantity of product, which is done by the PLC control.

5. Upon completion of this step, the dispenser stops dispensing. The operator transports the bag to the scales connected to the PLC, and with the help of a shovel, adds / reduces the product until the value specified in the PLC is obtained, which should be displayed on the display.

6. At this point, the marking device prints the marking with a barcode containing product data, the sign of the selling company and the date of manufacture,

7. The operator, using a stapler, performs the appropriate task and closes the bag.

8. The bag thus processed and sewn up is transported to a conveyor belt with a built-in barcode reader, and this information is transmitted to the PLC, while recording the presence or absence of problems when the bag passes through the detector. If there is a recurring problem, the bag is rejected.

9. After exiting the detector, the operator can see on the display how to palletize and how much should be placed on the pallet.

10. Upon receipt of the desired value, the operator performs a confirmation, and the device for making markings prints the marking for the pallet. The PLC logs all of these actions, including time values. At the same stage, after emptying the container, the discharge tray returns to the vertical position, at the same time the tray is separated from the container and the display shows whether it should be sent to the cleaning zone.

11. Cleaning zone: the container is to be cleaned by the PLC command displayed on the display near the cleaning stage, where the worker performing the cleaning is located, while monitoring the cleaning time.

All these records are stored in the PLC, which simultaneously performs interactive data processing.
